This commit changes the behavior of bml/r2 from conditionally registering btl progress functions to always registering progress functions. Any progress function beloning to a btl that is not yet in use is registered as low-priority. As soon as a proc is added that will make use of the btl is is re-registered normally. This works around an issue with some btls. In order to progress a first message from an unknown peer both ugni and openib need to have their progress functions called. If either btl is not in use after the first call to add_procs the callback was never happening. This commit ensures the btl progress function is called at some point but the number of progress callbacks is reduced from normal to ensure lower overhead when a btl is not used. The current ratio is 1 low priority progress callback for every 8 calls to opal_progress(). Fixes open-mpi/ompi#1676 Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov> |
